Abstract

713,472. Forging nuts. WATERBURY FARREL FOUNDRY & MACHINE CO. Jan. 4, 1952 [Jan. 16, 1951], No. 325/52. Class 83 (4) A method of making a polygonal nut blank includes cutting a workpiece from a length of solid rod or wire stock and the following coldforming steps in sequence : forming a shallow recess at one end of the work, chamfering the edge of the work at the other end and simultaneously deepening .said recess or compressing the work into shorter and wider shape, thereafter introducing the work into a die having side walls roughly corresponding to the final polygonal shape of the blank and forming the work into roughly polygonal shape and simultaneously forming a wide Chamfer at the recessed end of the work and an indentation having flared walls at the previously chamfered end of the work, whereafter the nut blank is completed in additional cold forging steps. A workpiece is cut from a length of stock 15 and transferred by a knife 16 to a die 19 where it is forged to the shape shown, Fig. 8. It is then transferred to a die 29 and provided with a chamber 37, Fig. 9, thence to a die 42, being inverted so that the chamfered end faces the punch 46, and the work is forged to the shape shown, Fig. 10, the chamber 37 allowing the punch 46 to enter and squeeze the work to provide the chamber 53 and recess 55. During transfer to the next-die 62, 63, which is carried in a spring-loaded holder 59, the work is again inverted. The work is forged in last mentioned die to finished hexagonal form, with a washer surface 73 and a thin web of metal between indentations 77, 78, Fig. 11. The said web is removed in the next operation by a punch 83. Plain face nut-blanks may be produced die parts 94, 94a, Fig. 16, being used at the fifth station instead of the die parts 62, 63. The transfer mechanism, Figs. 23-29 (not shown), is as described in Specification 671,016, whereby transfer fingers moving from the third to the fourth; and fromthe fourth to the fifth stations rotate through 180 degrees during such movements to invert the workpiece.
